Sub-eV Hubble scale inflation within gauge mediated supersymmetry breaking
Rouzbeh Allahverdi, Asko Jokinen, Anupam Mazumdar
Minimal Supersymmetric Standard Model with gauge mediated supersymmetry breaking has all the necessary ingredients for a successful sub-eV Hubble scale inflation $H_{\rm inf} \sim…
MSSM flat direction inflation: slow roll, stability, fine tunning and reheating
Rouzbeh Allahverdi, Kari Enqvist, Juan Garcia-Bellido +2
We consider low scale slow roll inflation driven by the gauge invariant flat directions {\bf udd} and {\bf LLe} of the Minimally Supersymmetric Standard Model at the vicinity of a…
Identifying the curvaton within MSSM
Rouzbeh Allahverdi, Kari Enqvist, Asko Jokinen +1
We consider inflaton couplings to MSSM flat directions and the thermalization of the inflaton decay products, taking into account gauge symmetry breaking due to flat direction cond…
Very Large Primordial Non-Gaussianity from multi-field: Application to Massless Preheating
Asko Jokinen, Anupam Mazumdar
In this paper we derive a generic expression, which is valid for scales larger than Hubble radius and contains only the local terms, for the second order curvature perturbations fo…
Supermassive gravitinos, dark matter, leptogenesis and flat direction baryogenesis
Rouzbeh Allahverdi, Steen Hannestad, Asko Jokinen +2
In general the gravitino mass and/or the soft supersymmetry breaking masses in the observable sector can be much larger than the TeV scale. Depending on the relation between the ma…
Cosmological constraints on string scale and coupling arising from tachyonic instability
Kari Enqvist, Asko Jokinen, Anupam Mazumdar +2
We demonstrate that string motivated inflation ending via tachyonic instability leaves a detectable imprint on the cosmic microwave background (CMB) radiation by virtue of the exci…
